Simulation of Microstrip LBPF with Sharp Roll-off and Wide Stop-Band Suppression

The design analysis of a lightweight micro-strip LPF with an ultra-wide rejection band is presented in this work. To accomplish steep roll-off and ultra-wide stop-band rejection, the suggested filter makes use of sophisticated resonator topologies, such as modified stepped impedance structures or tiny micro-strip resonant cells. Excellent harmonic noise suppression, reduced insertion loss in the pass-band, and a compact and small size make this structure ideal for contemporary microwave and radio frequency applications. Full-wave simulations and practical data are used to evaluate the filter design, demonstrating its outstanding sensitivity and scalability.
